Moment closure approximations of the Boltzmann Equation based on ϕ-divergences
M. R. A. Abdel-Malik, E. H. van Brummelen
This paper is concerned with approximations of the Boltzmann equation based on the method of moments. We propose a generalization of the setting of the moment-closure problem from…
